Sandhill Crane

Yesterday a couple of these birds showed up at my parents' house. Drove the dog crazy. At any rate, we quickly found out that they were Sandhill Cranes, some of the largest and most widespread Cranes in the entire world. They can be found across North America, in both year round and migrating populations. A Subspecies can also be found in eastern Siberia. There are about half a dozen location-based subspecies overall.

Sandhill Cranes are very tall, sporting a body length of up to 45in (1.1m). They have distinctive red caps and grey bodies that turn more brown during the breeding season (like those in the backyard).

Sandhill Cranes live, breed, and feed in grassland and wetland areas. They will eat just about anything, from snakes, to worms, to tubers dug up from the ground.

Pairs mate for life, and live together year round. During mating they practice "unison calling," which is an interesting coordinated duet. After mating a huge nest is built on the ground near water, using any materials the birds can find. Two eggs are laid at a time, and the female incubates while the male guards the nest. The chicks are very self sufficient at birth, and grow quickly (they fledge after about two months). Parents will then migrate along with their offspring, teaching them where to go. Interestingly, around 75% of all migrating Sandhill Cranes used the same 75 mile stretch of Nebraska's Platte River as a migratory staging area!

Because they are so common, Sandhill Cranes on the whole are not at risk. However, habitat loss has can have a massive effect on the species (especially when you consider the staging areas). Some of the southern subspecies are becoming quite rare. The Mississippi Sandhill Crane, for example, has a population of only a few hundred birds.

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a

Four!

For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!

Halloween Crab

Gecarcinus quadratus The Halloween Crab goes by many names, including the Red Land Crab, Whitespot Crab, and Moon Crab. I personally like Halloween Crab though, since it really reflects the interesting colors. They have black carapaces, orange-red legs, and purple claws! Halloween Crabs live in the Pacific coast mangroves and forests of Central and South America. They actually live in the forests as adults, and return to the ocean in order to reproduce. Did you know that they live as far away as 18 miles (30km)  from water? Not where you normally think Crabs to be! While living in the forest, the Crabs forage nocturnally for different plant matter, including leaves and sapling. They also dig long burrows into the ground for protection. These burrows can measure nearly 5 ft long! Halloween Crabs are sometimes kept in captivity, and can be very tricky pets due to their excellent climbing skills. IUCN Status :  Not Listed Location :   Cent
